STU Nl P=EXTRACTOR.

SPECIFICATION forming part of Letters Patent Nol 300,786, dated June 24,1884,

Application filed October 31, 1883.

To all whom it may concern:

Be it known that I, ROBERT M. McMnEN, a citizen of the United States,residing at Mount Vernon, in the county of Jefferson and State ofIllinois, have invented a new and useful Stump-Extractor, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to stump-extractors; and it has for its object toprovide a device which will be simple and durable in its construction,and have considerable lifting power; and a further object of theinvention is to provide means whereby the extractor may be readilytransported from ,place to place, as desired.

To attain these ends, the said invention consists in certain details ofconstruction and combination of parts, all as hereinafter set forth, andparticularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a side View of my improvedstump-extractor, and Fig. 2 is a plan View.

Like letters refer to corresponding parts in the several figures.

Referring to the drawings, A designates a suitable rectangular framemounted on wheels B B', the axle -O of the front wheels, B, beingattached to the cross-bar D by means of a king-bolt, E, while the rearaxle. F, is rigid with the frame. The obj ecty of this construction isto allow the rear end of the machine to' be held to the ground by meansof stakes, which brace the rear axle, the front axle being adapted to beturned at right angles to the rear axle, and held to the ground in anysuitable manner, the machine being held thereby in both a longitudinaland lateral direction, so that when in operation the strain ofextracting the stump will not detract from the steadiness of themachine, but the latter will be held in a secure and safe manner.

In the upper end of the frame A, near its center, is journaled a shaft,G, which extends transversely across the frame, and is provided at oneend with a spur-wheehH, engaging with a pinion, I, mounted at one end ofa shaft, J, the latter being arranged to extend across the machinebehind the shaft G. Said shaft .I is provided at the other end with aspur-wheel, K, engaging with a pinion, L, mounted on a shaft, M, thelatter being provided at its end opposite to the pinion L with aratchet-wheel, N, having pawl O engaging therewith., said pawl beingpivF (No model.)

oted by means of a pin or bolt, P, to the inner face of the frame. Theshaft M is provided at each end with cranks Q, by means of which themachine is operated. A cord, rope, or chain, T, is connected to theshaft G, and passes around a friction-wheel, R, mounted in the front endof the machine, and thus the friction caused by drawing the chain `willbe lessened, and a crank, S, is attached to the outer end of the 'shaftG, in order to unwind the chain upon the shaft preparatory to extractingthe stump.

The operation of my invention is obvious: Power is appliedk to thecranks Q, which impart motion to the shaft M. and by means of the pinionL, spur-wheel K, and pinion d this motion is transmitted to thespurwheel II, causing the revolution of the shaft G, and the consequentwinding of the chain around the said shaft, the stump being extracted bythis continual drawing of the chain. By means of the pawl and ratchet NO the shaft M will be held from turning back as it is wound, and thusthere will'be no loss inthe power of the machine.

The construction of the machine is simple, durable, and inexpensive, andits operation is efficient both in working and in its attainment ofconsiderable power.'

It will be apparent that various modifications may be resorted towithout departing from the spirit or scope of my invention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

In a stump-extractor, the combination of the frame A, mounted uponwheels, the front axle being adapted to be swung at right angles to theframe, and the rear axle being rigid therewith, with the shafts G J M,mounted in said frame, spur-wheels yH K, secured on shafts G J,respectively, pinion I, mounted upon shaft J and engaging with wheel H,and pinion L, mounted upon shaft M and engaging with spur-whee1 K, aratchet-wheel, N, secured to said shaft M, a pawl, O, engaging with saidratchet-wheel, a friction roller or wheel journaled in the frame, achain, T, and cranks S Q, as set forth.

In testimony that I claim the foregoing asmy own I have hereto affixedmy signature in presence of two witnesses.
